A bidirectional threaded rod 9 is rotatably connected through the mounting groove 8, enabling the external clamping column 13 to move relative to or away from each other. A knob 10 is fixedly connected to the right end of the bidirectional threaded rod 9, enabling the bidirectional threaded rod 9 to rotate. The outer ring of the bidirectional threaded rod 9 is threaded with clamping posts 13 on both sides. Multiple rubber strips (not shown in the figure) are provided on both sides of each clamping post 13 to better secure the bearing sleeve 14. Support columns 15 are fixedly connected to both sides of the top of the processing table 1, providing support. A drive assembly is located between the tops of the two support columns 15, and a lifting seat 22 is connected to the bottom of the drive assembly. The third motor 23 can be installed and fixed through the lifting seat 22. The third motor 23 is fixedly connected inside the lifting seat 22, and a grinding head 24 is fixedly connected to the output end of the third motor 23 through the lifting seat 22. The third motor 23 drives the grinding head 24 to rotate.

[0032] Reference Figure 3 The drive assembly includes a fixed base 16, with both sides of the bottom of the fixed base 16 fixedly connected to the top of the support column 15. A guide groove 17 is provided at the bottom of the fixed base 16, and a lead screw 18 is rotatably connected through the guide groove 17. A moving block 20 is threadedly connected to the outer ring of the lead screw 18. A hydraulic cylinder 21 is fixedly connected to the bottom of the moving block 20, and the output end of the hydraulic cylinder 21 is fixedly connected to the lifting base 22.

[0034] Working principle: When grinding the outer ring of the bearing sleeve 14 is required, the bearing sleeve 14 is placed on the outside of the two clamping posts 13. Then, the knob 10 is turned to drive the bidirectional threaded rod 9 to rotate. The bidirectional threaded rod 9 drives the two clamping posts 13 to move in opposite directions until the rubber strip on the outside of the clamping posts 13 contacts the inner ring of the bearing sleeve 14. The clamping posts 13 are spread open inside the bearing sleeve 14 to fix the bearing sleeve 14. After fixing, the limiting pin 12 is inserted through the corresponding through hole 11 on the knob 10 into the limiting hole (not shown in the figure) on the outside of the mounting base 7 for limiting. The outer ring of the bearing sleeve 14 can be ground using the grinding head 24. When grinding the inner ring of the bearing sleeve 14 is required, the bearing sleeve 14 is placed between the two clamping posts 13. Similarly, rotating the knob 10 drives the two clamping posts 13 to move relative to each other through the bidirectional threaded rod 9, clamping and fixing the outer sides of the bearing sleeve 14. The rubber strip can further improve the fixing effect of the bearing sleeve 14. During grinding, the hydraulic cylinder 21 drives the grinding head 24 below to a suitable position. Then, the first motor 2 is started to drive the turntable 3 to rotate. The turntable 3 drives the grinding table 5 and the fixed bearing sleeve 14 to rotate. At the same time, the second motor 19 drives the lead screw 18 to rotate. The lead screw 18 drives the moving block 20 to move left and right along the guide groove 17. The position of the grinding head 24 is adjusted according to the size of the bearing sleeve 14 until it abuts against the outer or inner ring of the bearing sleeve 14, thereby achieving grinding of the inner or outer ring of the bearing sleeve 14.
